What is Subnet Mask?


I can not use any of my browsers in Suse 10 so I bought a new External modem and the problem persisted. So I figured I must have a Virus of some kind so I took my computer to a shop and had my hard drive reformated again.

When I got hom my computer would connect to the Internet using windows but it's response was very slow. I could not get google mail to load up. I re-installed Suse 10 and the dial-up modem conected but I still could not use any of my browsers.

I clicked on the " connection information " and saw that my modem was connected to " Subnet Mask ".

What is Subnet Mask?

Has my phone line been tapped or compromised?

Is Verizon ( my phone company ) deliberately sabotaging my phone line in order to force me to pay for DSL or FIOS?

Which is better DSL or Road Runner with the cable company?

The frustration I am going through with this is shortening my life and realy bothering me. I hope someone knows what is happening and can explain it to me. Thanks!!!

A subnet mask is part of your TCP/IP address information; it is not something you physically connect to.

I have no idea about the tapping of your phone lines...but the rest of your problem is pretty much impossible to diagnose with the little information provided. The only thing we have to go on is that the connection is slow or does not work, which pretty much describes dial-up Internet access in general.

After almost two solid years of trouble free Linux os on the Internet this 63 year old computer illiterate had a panic attack and posted this thread. My tragic windows experiences flashed back into my head.

I spent $55.00 to have my hard drive reformatted again and to have my computer's serial port tested. When I brought it back home I re-installed Suse 10 and the U.S. Robotics 5686 modem dialed my ISP and connected to the Internet but none of my browsers would work.

I called the tech support phone number on the box the one month old modem came in and told the clerk what was happening. The clerk told me that I had to use the modem on a windows computer to connect to U.S. Robotics website so that the modem could be tested. I asked him if he realized just what he was saying. The clerk then informed me of U.S. Robotics company policies.

I ask for the mailing address so that I could ship the modem to U.S. Robotics and he refused to give it to me stating it was against company policy. I called the store where I bought the modem. That store has a 14 day return period. I had had the modem for a month so the clerk gave me the address he had on file to return U.S. Robotics equipment.

At the public library I went to Novells website where 5 external modems are listed. They are:

Ovislink of
U.S. Robotics 5630
U.S. Robotics 5686
Zoom 3049
Zoom 3048

Yesterday I bought a Zoom 3048 and I am thankfully back upon the Internet again.

I am going to ship my defective U.S. Robotics modem and a copy of the sales receipt to U.S. Robotics with a request that they find out what went wrong with their modem.

It will be interesting to see what kind of response they give to their defective modem.

That's weird - USR modems always used to be pretty solid and worked on Linux with little or no configuration.

If I bought the only lemon U.S. Robotics has ever produced so be it. I have to admit the last thing that I thought was wrong was a bum modem.

Subnet Mask

A subnet mask is basically just what it infers, it is a mask for networks. Just think of going to a restaurant with a bunch of your friends. Say, you have 3 sets of friends who need to reserve 3 tables with 4 seats to each table. You call the restaurant and say that you need to reserve 3 tables but then they ask you how many seats you need for each table. Well, this is kind of how a network mask works.

The reception desk will X out 3 tables on the floor and 4 seats to each table. By reserving 3 tables, they know that those 3 tables are already reserved and cannot be used. So if you reserve 3 octets the 3 octets are reserved by masking it out with the numbers 255. So 255 means this octet is reserved and cannot be used.

I hope this made sense and didn't confuse you ...

When I paniced there weren't any numbers on " connection information " and I thought my computer had been hijacked again. I guess I will never completely forget all the pain and suffering I went through using Windows on the Internet.

I am using a Zoom 3048 modem now and trying to calm down as I catch up on my email. I am hearing a lot about external modems now also after my 10 days of fright. One thing is clear - I am addicted to the Internet!!!

Well it turns out that even though I could hear the dial tone in my telephone; there was something wrong with my telephone line.

The threats this 63 year old man made about " an investigation needs to be made " about the way Verizon conducts business trying to force eveyone who uses dial up to get FIOS or DSL got some results.

Verizon called and said that the " line problem " has been corrected.

U.S. Robotics emailed me and gave me an RNA number and an address to send my defective modem to.

I have also been informed of the Actiontec V92 serial modem that sells for $20.00 ( plus a $7.00 shipping charge ). So there was some " silver lining " to my latest intense dark cloud moment.

Excellent news (though it obviously took too long to get made right) for you. It's always good to know that a fault isn't at your end!
